Japan's national police organization is made up of the National Public Safety Commission (NPSC) and the National Police Agency (NPA). The NPSC holds administrative supervision over the NPA and appoints the Commissioner General. As head of the NPA, the Commissioner General 警察庁長官 (Keisatsu-chō Chōkan) holds the highest position in the Japanese police, but his title is not a police rank.
The NPA oversees the seven Regional Police Bureaus (RPB) and the prefectural police organizations. Tokyo Metropolitan Police Department (警視庁 Keishichō) and Hokkaido Prefectural Police Headquarters are excluded from the jurisdiction of RPBs. Police stations in a prefecture are under the command of the prefecture headquarters. Tokyo MPD headquarters are located in the government buildings area beside the Imperial Palace in Chiyoda-ku, Tokyo.
 Police Department Sections
Police Station personnel are divided into seven departments or bureaus:
- Administration Department
- Traffic Department
- Security Department (Security for domestic and foreign dignitaries; also subversive activities and counterintelligence)
- Junpei Matsuda was on the bomb squad in this department.
- Community Police Affairs Department
- Police Boxes (Koban)
- Residential Police Boxes (Chuzaisho)
- Patrol cars
- Criminal Investigation Department (刑事部 Keijibu)
- Community Safety Department
- Organized Crime Control Department
Within departments, there may be specialized units, such as the Identification Division that collects crime scene evidence. 
 Police Ranks
There are nine legal police ranks and one honorary rank for all positions within the police force. 
 Superintendent General (Rank 1)
警視総監 (Keishi-sōkan) is the highest police rank and the head of the Tokyo Metropolitan Police Department, the largest prefectural-level jurisdiction in Japan. This position is currently held by Saguru Hakuba's father.
 Superintendent Supervisor (Rank 2)
警視監 (Keishi-kan) is equivalent to:
- Deputy Superintendent General
- Director General of a Regional Police Bureau or an NPA Training Department Bureau
- Chief of a (large) Prefectural Police Force
 Chief Superintendent (Rank 3)
警視長 (Keishi-chō) is equivalent to:
- Chief of a (smaller) Prefectural Police Force
- Director in the NPA
 Senior Superintendent (Rank 4)
警視正 (Keishi-sei) is equivalent to:
- Director of a department in a prefecture police headquarters
- Toshiro Odagiri, Chief (部長 buchō) of the MPD Criminal Investigations Department (警視庁 刑事部 Keishichō keijibu)
- Ginshiro Toyama is the Osaka Prefecture Police Chief Criminal Investigator (刑事部長 keijibuchō)
- Masayoshi Sato held this rank in the Tokyo MPD before he passed away, presumably in C.I. and replaced by Odagiri.
- Chief of a larger police station
 Superintendent (Rank 5)
警視 (Keishi) is equivalent to:
- Director of a division/section in a prefectural police headquarters
- Kiyonaga Matsumoto, MPD Superintendent (警視庁 警視 Keishichō keishi). Presumably, director of Criminal Investigations Division 1 (捜査 一課 Sousa itsuka), as he is Inspector Megure's superior and Miwako calls him Director (管理官 kanrikan).
- Shintaro Chaki, MPD C.I. Division 2 Superintendent (警視庁 捜査 二課 警視 Keishichō sōsa nika keishi).
- Chief of a police station
 Police Inspector (Rank 6)
警部 (Keibu) is attainable in the early 30s via successive promotion tests and is equivalent to:
- Chief of a section in a police station (i.e., homicide) or other field unit supervisors in those sections
- Juzo Megure, Inspector and unit supervisor in the Criminal Investigations Division 1.
- Ninzaburo Shiratori, starting from his first manga appearance, previously Assistant Police Inspector.
- Ginzo Nakamori, MPD C.I. Division 2 
- Yuminaga is an Inspector in the Arson section of C.I. Division 1.
- Momose is a Tokyo MPD Inspector covering Theft
- Chosuke Takagi is presumed to be Inspector rank because he is Megure's senior by two years, yet Matsumoto speaks of him subordinately, and he is mobile enough to be transferred to Tottori but high enough to represent MPD HQ C.I. in Tottori.
- Ayami Ogino, Saitama Prefecture Police
- Sango Yokomizo, Shizuoka Prefecture Police (previously Inspector in the Saitama Prefecture)
- Jugo Yokomizo, Kanagawa Prefecture Police 
- Taka'aki Morofushi, Nagano Prefecture Police (recently instated)
- Kansuke Yamato, Nagano Prefectural Police (promoted in-series)
- Misao Yamamura, Gunma Prefecture (promoted in Movie 13).
 Assistant Police Inspector (Rank 7)
警部補 (Keibu-ho) is attainable via promotion tests. Officers at this rank and potentially below can be referred to as 'keiji'.
- When Conan impersonates Takagi, he calls Miwako Sato keibu-ho. Given that she and Shiratori both believed the impersonation, it must be accurate.
- Chiba holds this rank in Criminal Investigation Division 1 if you assume that 三係 (san-kakari) means third rank, and thus this level, as he and Miwako both are described this way. More specific reference needed, as this could also refer to the unit led by Inspector Megure.
- Yumi Miyamoto refers to Wataru Takagi once as keibu-ho, possibly as a future reference. After Takagi allows a criminal to be killed under his watch, he is definitely a junsa-bucho, but whether he received a pay dock only or a demotion as well is unclear.
- Yumi Miyamoto, MPD HQ Traffic Division, wears the official uniform rather than plainclothes but is an Assistant Inspector. Either the traffic division is required to wear the uniform on patrol, or she prefers the uniform for personal reasons.
 Police Sergeant (Rank 8)
巡査部長 (Junsa-buchō) is attainable via promotion tests.
- After the bullet train fiasco where Takagi was lucky to not get fired, Miwako refers to Takagi as junsa-bucho.
- Naeko Miike, who transferred to the MPD HQ Traffic Division from Haido Station, is a patrol officer who wears the uniform but who has also achieved Police Sergeant status due to the bars on her uniform badge.
 Senior Police Officer (Honorary)
巡査長 (Junsa-chō) is not a legal rank, but is bestowed on officers with years of experience and excellent work. These officers are often responsible for training and mentoring junior officers.
 Police officer (Rank 9)
巡査 (Junsa) is the most junior rank.
 Unconfirmed Ranks
- Yui Uehara of Nagano Prefecture is a lower rank than Kansuke's Inspector status, but as a keiji she is likely an Assistant Inspector.
- Jinpei Matsuda was a keiji, but a given rank has yet to be found.
